Description

Technical Field

[0001] The utility model relates to the technical field of grinding tool preparation, in particular to a grinding wheel forming die pressing head with adjustable height. Background Art

[0002] In the process of preparing grinding wheels, molds are generally used to press the molding materials into shape. The mold material is mostly mold steel, and a set of molds includes a mold sleeve, a mandrel, a lower pressure plate, an upper pressure plate, a pressure head, etc. The molding methods of grinding wheels include fixed pressure molding and fixed mold molding.

[0003] The fixed pressure molding method is used for grinding wheel molding, that is, the grinding wheel volume is fixed during molding (mainly controlling the thickness size), the pressing force (generally called unit pressure) is specified to press the grinding wheel, and the molding weight can be increased or decreased. In this way, the pressing head of the mold does not need to be replaced in large quantities. Such operation is generally suitable for grinding wheels with fewer varieties and larger specifications. Its advantages are simple mold management and general use. During molding, the adverse effects of inaccurate scales on the product can be avoided, and pressurization automation can be realized. Its disadvantages are that it is difficult to control the organization number and the hardness also fluctuates greatly.

[0004] For grinding wheel molding, a fixed mold molding method is adopted, also called fixed volume molding, that is, the molding weight is specified during molding, and a certain volume is pressed out (mainly to control the thickness), but the molding pressure is not specified. Its advantages are that the organization of the mold can be controlled, the hardness is relatively stable, and the influence of the offset caused by the press can be eliminated. Its disadvantages are that the mold management is more complicated, the balance and scale require more accuracy, the mold wear and dimensional tolerance requirements are stricter, and it is not convenient for automatic molding. A set of molds to mold grinding wheels of different thicknesses requires the constant replacement of pressure heads of different heights. Due to the wide variety of small grinding wheels, the number and variety of pressure heads are many, which makes it more difficult to use and manage, and the cost of the mold will also increase significantly.

[0005] In order to solve the above problems, the applicant provides a grinding wheel forming mold pressure head with adjustable height, which is suitable for the production of a wide variety of small-sized grinding wheels. It can not only adjust the height to meet the requirements at will, but also is easy to operate and manage. The mold cost is greatly reduced, which is convenient for promotion and application.
